same cylinder, that the exhaust-port in the valve will register with theexhaust-port in the cylinder-head and again be closed immediately beforethe cooperating inlet-ports of the same cylinder are brought inregister.

The exhaust-recesses of the valve extend for about one-third of theperiphery of the valve so that ample exhaust is provided.

In practice, the fuel inlet is opened to the 1 supply which is acarbureter of any suitable construction, not illustrated, or other gassupply, and the fuel flows into the valve and, when the engine isstarted, flows through one of the inlet ports into one cylinder in Whichthe fuel is compressed and ignited and the piston in said cylinder isforced downward. When the piston again ascends,

the exhaust-ports are openand the spent gases are exhausted, until thepiston arrives at the upper end of its stroke -when the inlets are againbrought in communication and fuel drawn into the cylinder and againcompressed When the piston again ascends and is ignited when the pistonarrives at the upper end of its stroke. This operation is performedsuccessively in the several cylinders, so that three explosionssuccessively-- The exterior of the valve Will be peripherally narrowinlet ports admit of fuel being quickly and in large quantities fed intothe cylinders, and the narrow and peripherally long exhaust ports andrecesses admit of thorough exhaust of the spent gases. 'The rotatingvalve will be noiseless andwvill not be liable tOj,bQ obstructed or haveimpurities collect tof gca useleaks, as is liable to happen with theusual pop-valves, as the valve is continually in motion so long as theengipe is in'motion.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is
